This invention relates generally to devices for dispensing gasoline, .and particularly to that class of devices vin which gasoline is .pumped from an underground storage and ilelivered to the consumers tank through a ose.

The main object of this invention is to provide a dispensing unit in locations not justi? fying the presence of a regular attendant for the purpose of rendering service and taking care of the transactions.

The second object is to provide a dispensing unit especially designed for use on aviation fields.

The third object is to provide a dispensing unit which will be adapted for use in large service stations having a number of attendants, or in garages for taking .care of important accounts.

The fourth object is to adapt same for use by large business houses having numerous motor cars for the purpose of making it possible to keep an accurate record of the gasoline used by each of its units.

These, and other objects, will become more apparent from the specification following as illustrated in the accompanying drawing, in which: y

Figure 1 is a front elevation of the device. 30 Figure 2 is a horizontal section taken along the line 2 2 in Figure 1. Figure 3 is a rear elevation of the registering portion of the device. Figure 4 is an enlarged section through one of the locking mechanisms. F ig- 35 ure 5 is a section taken along the line 5-5 in Figure 4. Figure 6 is a somewhat diagrammatic side elevation of the gearing employed in the device. Figure 7 is a vertical section takenalong the line 7 -7 in Figure 6. Figure 8 is 'a` wiring diagram showing the manner of operating the device. Figure 9 is a fragmentar elevation of a single key-hole taken along tlie line 9-9 in Figure 4. Figure 10 is an enlarged view of pinion and gear showing form of teeth.

Similar numbers of reference refer to similarparts throughout the several views.

Referring in detail to the drawing, there is shown the usual frame 10 in which is 5 mounted a pump 11 fromwhich gasoline is normally lock the bearing 37 stationary. A

drawn from an underground tank (not shown) through a pipe 12 and delivered through a meter 13 to a dispensing hose 14 and filling nozzle 15. The illing nozzle 15 is provided with a cut-off valve 16 controlled by a trigger -17 which closes a switch 18 on the nozzle 15 normally starting the motor 19 whenever the trigger 17 is operated to open the valve 16.

The measures of gasoline dispensed are indicated .on the dial 20 by means of the gallon hand 21 and the quart hand 22, as is now the common practice. The hands 21 and 22 are mounted on the shafts 23 and 24 which are driven from the meter shaft 25 by the usual form ofgearing (not shown) On the shaft 23 is secured a gear 26 which meshes with a pinion 27 which is in turn mounted on a stud bolt 28 on the casing 29. Thel gear 26 is pinned or otherwise secured to the shaft 23. Loosely mounted on the shaft 23, outside of the gear 26, is a combined internal and external gear 30 whose internal teeth 31 mesh with the pinion 27, and whose external teeth 32 are normally out of mesh with all of the pinions 33 disposed around the periphery thereof on the slidable shafts 34, one end of which journals in the bearings 35 and contains the spring 36 which urges the pinions 33 out of mesh with the teeth 32.

The opposite end of each shaft 34 journals in a rotatable bearing 37 in whose shank 38 are a plurality of locking tumblers 39 which key 40 is employed to release the tumblers 39, thereby freeing the bearing 37 as Well as pushing the shaft 34 sufficiently far to bring its respective pinion 33 into mesh with the teeth 32 of the gear 30. The key when inserted in its lock must pass through the slot 41 in the front 42 so that when once the key is turned away from its starting position it cannot again be pushed outwardly by the spring 36until it is restored to its starting position.

While the tumblers'39 will correctly position each of the bearings 37 when the pinion 33 is inoperative, it is evident that provision must be made to hold the` bearing 37 against 30 rotation when its associated parts are in an operative position. For this purpose there is provided a spring-urged pin 43 within the bearing housing 44, and a corresponding recess 45 within the bearing 37 which is not sufficiently deep 1to lock the parts together, but merely to hold same more securely than they would be held by friction.

On each shaft 34 is formed a cam arm 46 which engages the arm 47 of a counting mechanism 48 which is carried by the bearing 37. The front 42 is provided with windows 49 through which the numbers 50 of the counting mechanism are visible only ywhen the key 40 has been turned to an unlocked position, due to the fact that when the key 40 is turned to a locked position then the numbers 50 move away from their respective windows 49.

On the inside of the front 42 arethe pillars 51 which carry a circular contact support 52 on which is mounted a rigid inner contact 53 and a flexible outer contact 54, which are normally separated from each other, but may be brought into contact with each other by an external pressure against the outer member 54. This is accomplished by providing an eccentric portion 55 on the bearing 37 so that when the key 40 is turned to an unlocked position a Contact is made across the members 53'and 54. The contact 53 is joined bythe wire 5o to the switch 18 on the nozzle 15. rIhe contact 54 is oined by a wire 57 to the motor 19. The wire 57 includes a contact switch 58 which is close to the door lock 59 between the sections 60 and 61 which are joined by the hinge 62. A wire 63 connects the motor 19 to a source of power 64 from which it is connected to the second side of the switch 18.

'Ihe operation of the device is as follows: If, for example, a pilot should wish to draw a supply of fuel he merely inserts his key 40 into the particular key-hole assigned to him and turns it, thereby exposing the numbers 50 on his own register or dial to view, and at the same time closing one portion of the motor circuit by means of the eccentric 55. It will be remembered that the other side of the motor circuit is under control of the trigger 17 which operates the switch 18. When he attempts to draw gas from the lling nozzle 15, thereby starting the motor 19 which draws the gasoline from the underground tank through the pipe 12, it'forces it through the meter 13 and displaces first any gasoline which may remain in the hose 14, and thenv continues to iow as long as the trigger 17 is depressed, during which time the meter 13 is causing a visible indication of the volume of fuel drawn, by means of the hands 21 and 22, which are of course restored to a zero position at the close of the drawing.

Not so, however, with the numbers on the counting mechanism 48 which keep a total of the amount of gasoline drawn for the particular person or piece of equipment represented by the various key-holes, in this instance numbered from 1 to 12 respectively, although of course the actual names of the users could be supplied if desired, and the number of such key-holes can also be varied to suit the requirementsl of the particular unit in question.

While this device has been illustrated as` being entirely above ground, it can easily be understood that for landing fields it would in many instances be desirable to provide an entirely flush unit over which planes could pass without danger to the plane or dispens- -u 4cover all forms and modifications of this device as fall fairly within the appended claims.
